Use P0.05 AIN3 as outuput

[Epasta]

Hello all,

I'm trying to use P0.05 (AIN3) as output, but it does not work.

in file .dts is used as:
rts-pin = <5>;
status = "okay";
of uart0, I have to change this config? 

This is my code for putting pin 5 HIGH:
#define LATCH 5
#define ON 1
gpio_pin_configure(dev, LATCH, GPIO_OUTPUT); 
gpio_pin_set_raw(dev, LATCH, ON);

All other pins (for example 29, 13,  24, 9, 16) works well. Do you have some suggestion for me?

P.S. I'm using nrf connect sdk 1.6

Thanks
best regards

Check out nRF52840 DK --> Interface MCU --> Virtual COM port. It says the P0.05 used as UART RTS and connected to the interface MCU.

Take a look at nRF52840 DK --> Hardware description --> Solder bridge configuration: 

So you have to cut SB51 on the nRF52840 DK to use it as a regular GPIO.

Best regards,

Simon
